Carotenoid Pigments of Mycobacterium kansasii

Hugo L. David

Center for Disease Control, Atlanta, Georgia 30333

ABSTRACT

Partitioned between aqueous methanol and petroleum ether, the unsaponifiable pigments of Mycobacterium kansasii were all epiphasic. Thin-layer chromatography of these carotenoids showed that M. kansasii formed at least nine pigments. These pigments were identified by their chromatographic properties and spectral characteristics as phytoene, {zeta}-carotene, neurosporene, lycopene, leprotene, {gamma}-carotene, {delta}-carotene, {alpha}-carotene, and ß-carotene. Three additional pigmented spots on thin-layer chromatography found in trace amounts were possibly degradation products of the major carotenoids.
